Having driven EV for several winters now, as well as cars shows out of my range, I do not leave home without my generator in the car. I have only used it four times this year, since I made the metal plate that attaches to my hatch and rests on my bumper, but I have a lot more peace of mind with it in the cars. I personally would not leave home without a generator in the winter, when going to places I am not familiar with, or places slightly out of my range.
